Abstract	In high-speed machining process, in order to improve the machining accuracy, the velocity should be optimized flexibly in advance. The s-curve acceleration and deceleration control mode was more used in velocity control than others. Based on the essential principle of the s-curve acceleration and deceleration control mode, the pre-interpolation acceleration and deceleration control was adopted to work out the relevant motional parameters of different program blocks. Using the look-ahead method, the adaptive acceleration and deceleration was introduced to evaluate the data far in advance and adjust the feed rate. The adaptive velocity control method is simulated and the result shows that the velocity curve is smoother and the machining time is shorter than traditional method. The velocity control of NC machining is solved effectively and the machining accuracy and productivity will be improved greatly.
